| 摘 要： | 从船舶操纵模拟器的地形要求出发,以等高线图为原始数据,对其进行扫描矢量化,利用不规则三角网法差值计算生成DEM,然后使用Multigen Creator 3维建模软件生成地形.重点研究了可视化需要调节大地形的模型精细度、真实性和实时系统运算能力之间的协调关系.最后,以鸭绿江河段和图们江河段为研究区域,建立了直观的3维地形模型.

| Abstract: | According to the requirement for the terrain modeling of the ship handling simulator,firstly,scan and vector the primal data whose form is the contour line map;secondly,use the irregular triangular net-work to create DEM;finally,the terrain modeling is created by the software of Multigen Creator.The emphasis is on the compromise relation between the elaborate extent of modeling and the operation efficiency of computer system.In this thesis,the reach of Yalu and Tumen River were taken as the investigative re... |
